Service Precautions. Chevrolet PJJ 2000

For 1990-2009 cars

Observe the following general precautions during any ABS/ETS service. Failure to adhere to these precautions may result in ABS/ETS system damage.

• | Disconnect the EBCM harness connector before performing electric welding procedures.

• | Carefully note the routing of the ABS/ETS wiring and wiring components during removal. The ABS/ETS components are extremely sensitive to EMI (electromagnetic interference). Proper mounting is critical during component service.

• | Do not use a quick charger for engine starting or for battery charging with the battery still connected. Brake failure or ABS/ETS component damage may result.

• | Disconnect the battery with the ignition OFF.

• | Disconnect the EBCM connector with the ignition OFF.

• | Do not attempt to repair the BPMV or any other non serviceable ABS/ETS components where noted in this section. Many ABS/ETS components are serviceable by component replacement only.

• | Do not hang the suspension components from the wheel speed sensor wiring. The wiring may be damaged.

• | Do not subject the EBCM to temperatures of more than 85°C (184°F).

• | Do not use petroleum based fluids in the master cylinder. Do not use any containers previously used for petroleum based fluids. Petroleum causes swelling and distortion of the rubber components in the hydraulic brake system, resulting in water entering the system and lowering the fluid boiling point.

• | Inspect the ABS/ETS system after service using a scan tool.
